' The invention relates to machines for forming journal bearing linersegmentsand more particularly" to .ameans for accurately sizing such segments so as to adapt the same for exchangeableuse in journal bearings of predetermined dimensions. In the present. state of the art it is usual to provide journal boxes or bearings, with exchangeable segmental liners; which vform the actual bearing surface. These liners areformed of various materials and by Various methods, but

beforethey can be used must lie-accurately sized.

It is also customary to form such bearing liners of an original-diameter somewhat in excess of the dimension, they? assume whenplaced in the bearing, so'that the resiliency of the material will tend toholdfithe liner in close contact with the surrounding supporting structuren-Thusi if the liner segments asoriginally formed are ap proximately .one-half' the circumference of a V circle, their: longitudinal edges mustbe trimmed to size each segment to .a bearingofsmaller radius. Grreat accuracyin this sizing is required;

asotherwi'se'the'liners might be either, too loose which ,is objectionable, or too tight to cause a pinching of the journal. I

It is the object of the instant invention to provide a-machine which will automatically operate with great rapidity on liner segments as orig-v' inally formed, accurately sizing and then deliver in'g thefsame'."

3 and 4) on the frame A Provision isE'a'lso, made I for a slight vertical adjustment of the supp rt ing way E for the purpose of,v adjusting the work on the carriage in relation to the cutting tool.

Such adjustment is accomplished'by forming the way 12. with a longitudinally inclinedlower surface E engaging a corresponding inclined'bearing on the. frame A. A screw'threa'ded linked rod E at the; end of the way E asses through a bearing. on the frame and threaded collars E and E on opposite sidesof said bearing serve as an adjustment means. One' of these collars may be calibrated as shown at E soras torindt is coupled by a rodjL' with a. rack L horizontally slidable in a guideWayL gThe rack L is prefer; ably='-formed of two laterally spaced members between which areivertically'extendingracks L? andL also suitablyguided. L and L are pinions which are journaled inthe carriage E and are positioned to be in mesh respectively with the. racks L and L and also are ofa-length' to be inmesh withboth spaced membersof therack Thus; the horizontal movement-of the rack L? under the actuation'of the piston will be concate the exact amount thatthe carriage will be Y raised in the .rotative adjustmentof the collar. A clampingplate E holds the way E3 rigid after each adjustment. To permit of vertical movement of the carriage when the wayE is adjusted, a shoe E extending along the upper face'of the frame E" is yieldably pressed against the bearing E by springs 151 The ways E and E are preferably obliquely inclined'in ;cross section. This will hold the carriage frame E in close contact with-the vertically extending way E atits upper end and ,a vertical'way E at its lower end,

thereby insuring a very accurate movement -of the carriage along a, predetermined path.

Loading mechanism V The worm gear wheel G" (Fig. 10) has mounted upon oppositesidesjthereofcam members I and I, preferably clamped theretogby bolts I? passing through slots I in thewebof the wheel;- This permits of a slight rotative adjustment of the cams for proper timing of the same. The cam I (Fig. '7) actuates a bell crank levenK. which-is f r me ne inKiand ha ar e r ipe: ripherally engaging the cam. {The ot the bell crank lever terminates inga positioned that at a predetermined time the roller K following a depressed portion I in the cam I will cause an upward movement of .the rackiii, rotating the pinion K and shaftK and swin ing the arm C to carry a liner segment from the chute into engagementwith the female dieID.

This is facilitatedby relieving the inner surfaceof the sleeve centrally at L and in; its 7 bearing;portionsL of only-limited area. The

screws; L are located atthe opposite ends'ofthe sleeve; soias to be beyond the. ends of thefemale die-' 1 t When the racks L andL are drawn downward into their lowermostposition. this through the links I} and will-draw downthe core member, thereby clamping "the bearing segmentin the female die.

4 Cleaning of the bearingse gm'ents and the To secure accuracy in the sizing of the -bar- 7 ing segments the surface which contacts the die must befree from any dust or particles .of any character which mighthold it out 'of position. A1so, the surface of the die must be equallyclean.

The cleaning of the bearing segments is effected during transfer of the same by the loader, this being accomplished by an air jet Q (Figs. 2 and- 22) so directed as to impinge against the outer convex surface of the segment'during such travel.
